Self-made python script to monitor Esxi underlying DELL hard disk (using python with its own module paramiko)

[root@localhost libexec] # cd / usr/local/nagios/libexec

[root@localhost libexec] # vi datadomain.py

#! / usr/bin/env python

Import paramiko

Import re

Import sys

# 0 ok; 1 warning; 2 critical; 3 unknown

Ssh = paramiko.SSHClient ()

Ssh.set_missing_host_key_policy (paramiko.AutoAddPolicy ())

Ip = "10.10.254.11"

User = "sysadmin"

Passwd = "1111111111111111"

Ssh.connect (ip,22,user,passwd)

Stdin,stdout,stderr = ssh.exec_command ("disk status")

Outmsg,errmsg = stdout.read (), stderr.read ()

Keyvalue=outmsg.find ('7')

If int (keyvalue)-1:

Print "Disk ok!"

Sys.exit (0)

Else:

Print "Disk goes wrong!"

Sys.exit (2)

Ssh.close ()

Script note: when keyvalue is equal to-1, the quantity is not 7, that is, there is a problem with the hard drive.

Add commands to commands.cfg first.

[root@localhost libexec] # vi / usr/local/nagios/etc/objects/commands.cfg

Define command {

Command_name datadomain

Command_line sudo $USER1 $/ datadomain.py

}

Add the following to nagios.cfg

[root@localhost libexec] # vi / usr/local/nagios/etc/nagios.cfg

Cfg_file=/usr/local/nagios/etc/objects/datadomain.cfg

Define hosts and services: create a new datadomain.cfg in / usr/local/nagios/etc/objects

[root@localhost libexec] # vi / usr/local/nagios/etc/objects/datadomain.cfg

Define host {

Use EMC DataDomain 2200

Host_name EMC DataDomain 2200

Alias EMC DataDomain 2200

Address 10.10.254.11

}

Define service {

Use generic-service

Host_name EMC DataDomain 2200

Service_description EMC DataDomain 2200

Check_command datadomain

Notifications_enabled 1

}

Then you must add the following to the templates.cfg

[root@localhost libexec] # vi / usr/local/nagios/etc/objects/templates.cfg

Define host {

Name EMC DataDomain 2200; The name of this host template

Use generic-host; This template inherits other values from the generic-host template

Check_period 24x7; By default, EMC DataDomain 2200 hosts are checked round the clock

Check_interval 5; Actively check the host every 10 minutes

Retry_interval 1; Schedule host check retries at 10 minute intervals

Max_check_attempts 10; Check each EMC DataDomain 2200 host 10 times (max)

Check_command check-host-alive; Default command to check EMC DataDomain 2200 hosts

Notification_period workhours; EMC DataDomain 2200 admins hate to be woken up, so we only notify during the day

; Note that the notification_period variable is being overridden from

; the value that is inherited from the generic-host template!

Notification_interval 120; Resend notifications every 2 hours

Notification_options djingheng r; Only send notifications for specific host states

Contact_groups admins; Notifications get sent to the admins by default

Register 0; DONT REGISTER THIS DEFINITION-ITS NOT A REAL HOST, JUST A TEMPLATE!

}

Add sudo permissions

[root@localhost libexec] # visudo

Nagios ALL= (ALL) NOPASSWD:/usr/local/nagios/libexec/datadomain.py
